How can i use pushbutton callback in opening function callback?

I have a very long script file.But inorder to fix it in GUI, i have divided it into small functions. The program starts with GUI and few functions are written in opening function. When i click on push button callback function, i want one function to be called. But when i do this it gives me error. I think the values inside variables are not reaching the function because it gives me errors related to undefined variable, etc. What is the solution to this problem.

check if the corresponding callback function for the push button is being called or not

Those variables are local to the opening function and thus the scope is limited to opening function only. See this How can I share data between callback functions in my GUI(s)?

it doc helped me.. but i have a doubt is it possible to create a gui fn with input paramters and without output parameters? I tried,

function varargout = gui3(actualv, Lsoftv, EVnew, EVold,I1)

and the error i got was:

Undefined variable varargin.

Error in gui3 (line 42) gui_mainfcn(gui_State, varargin{:});
